[R-sig-ME] Using variance components of lmer for ICC computation in reliability study

[Pierre de Villemereuil]

Hi,

> Maybe there is information about the residual variances in the 2-threshold model in such a setup?

Maybe, but it would be quite hard (if possible at all) to distinguish from changes in the mean, wouldn't it? Unless the changes in the "spreading" are quite dramatic and located in the extreme categories with a strong "depletion" from the central one. 

It's interesting to think about it though.

Cheers,
Pierre.
